Question

I’ve inherited some javascript, and it’s not all working as expected at the moment. This is one sticking point:

jQuery("#theForm")
  .find("input[@checked], input[@type='text'], options[@selected], textarea")
  .each(function() { ... });

I’m not familiar with the [@] syntax (though it seems clear what it wants to have happen), and I’m not finding documentation. Can anyone tell me if this is valid jquery?

The @ is an xpath selector (has attribute), which has been deprecated since jQuery 1.1.4. Just leave it out, or replace those with pseudo-selectors:

jQuery("#theForm")
.find("input:checked, input:text, option:selected, textarea")
.each(function() { ... });
